Supercharger Tuning Poll

I was wondering if all you Supercharged Maxima owners who have upgraded your pulleys for more boost would car to share some information.

What Gen? 4th or 5th
What SC kit? V1 or V2
What pulley?
What actual boost level at redline?
What FMU disc? stock or 8:1
Peak EGT readings after a full run?
Fuel pressure at full boost?
Spark plugs? Stock, one step colder...
Track times or dyno numbers?
Any other usefull tuning info.

I'm doing a little research....

Re: Supercharger Tuning Poll

What Gen? 4th
What SC kit? V1
What pulley? 3.25
What actual boost level at redline? 8.5psi
What FMU disc? 8:1
Peak EGT readings after a full run? 720c
Fuel pressure at full boost? 90ish
Spark plugs? NGK BKR7E two step colder
Track times or dyno numbers? 13.6@102

I ran 13.6 with one step colder plugs.
I pput the 6:1 fmu disc in last night and the car seems MUCH faster. EGT's were 780-790c after a full run.

What are you researching? PM me if you don't want to post it here.

How did the car run on the 6:1 disc and the stock pulley? Maybe Mardi should include emissions test too. ie.. ran rich on 6:1 or lean etc..So stock sc is about 8 psi? Hmmmm.

Where can I get some fittings for the in/out lets on the Vortech FPR?

Any store?

I never ran a stock pulley

Stock is suposed to be ~6psi peak at shift point.

It is leaner on the 6:1 but not soo much that it is detonating.

You can get fittings for the Vortech FMU from most autopart stores or even home improvment centers. The female threads on the FMU are 1/8" NPT. Then you just need to know what your comming out to, hose or pressure fitting. I just used high pressure fuel injecton hose. I forget what size but it should be the same as stock. Take a piece off and bring it with you to the store to be sure you get the right size.

6 psi? Even better! Thanks for the info. I think I've seen these fittings at the Home Depot or something. Napa carries good fuel injection hoses.

Hey when you guys are seeing high EGTs, are your water temps increasing also? Or are you guys raising the EGTs too fast for the water temps to start reacting??

Is the 8:1 disc going to make my car run too rich? I have the 3.33 pulley. I also have nitrous, so I'm not sure.

These are EGT spikes at full throttle. Normal NA Maxima EGTs are ~770c at full throttle in third or fourth gear.

If it runs fine with the 6:1 I'd stay with that. But as you get close to 10psi of boost the 8:1 may be necesary. With an EGT gauge or near wide band A/F gauge or some dyno tuning you will know for sure.

EGT gauge is on the way. So I guess I'll find out soon. What's a good temperature range?

My Max with I,Y,E and one step colder plat. plugs, peaked at ~770c at the 1/4 mile traps.

My Max with I,Y,E + 100hp nitrous and one step colder plat. plugs peaked at ~810-820c at the 1/4 mile traps.

With 8.5psi of boost, 8:1 FMU disc, and and two step colder copper plugs I got 700c-710c at the 1/4 mile traps.

With 8.5psi of boost, 8:1 FMU disc ,35hp shot of just dry nitrous and two step colder copper plugs, I got ~720-730c at the 1/4 mile traps.

With 8.5 psi of boost, 6:1 FMU disc and and two step colder copper pligs, I got 780-790c at the 1/4 mile traps.

As a reference to A/F ratios when I dynoed with my 100hp shot I got ~12.4:1 A/F ratio. So you could assume that 810-820c is ~12.4:1 A/F Ratio.

Another SC member got 11.8:1 A/F ratio and was at 730c.

You can see how their related.

Have a way to check the A/F ratio using a wide band sensor or EGT gauge I would say 8:1 to be safe.

Gettin an a/f gauge before I do anything along with boost. Kev was saying get the 8:1 so thats what I was planing but sombody said the car was faster with 6:1 so just thought i'd put it out there to see what others thought.

It's just real fuct up on how he lost control, and nailed a neighbors car, and his house was only up the street. Police report says, "Speed contest @ 75-85 mph when he went for fairly sharp right hander, misjudged where the curb was, and his rear slid out, and over compensation to the wheel, he plowed into his neighbors S4. His seatbelt buckle had broke, and the impact of the airbag @ 65-75 mph w/ practically no belt, you know what can happen.
Eclipses have a "cockpit" style interior and his motor was literally in the passenger seat. I won't get into the rest, but when I saw the car yesterday, scares me.

I'm sorry about your friend but I think something good can come out of it. Why not make this a sticky or somthing to draw everybody to look at it. Maybe just maybe some of those guys that keep talking about how they weve in and out of traffic at 120mph will stop and we can save a life or two. Again I'm sorry about your friend I know what its like to loose people suddenly do to speed and thinking they can do things they can't.

After watching The Pike video over and over again, it made me regret alot of things I did that night, and it the way things have been happening around me, and on Maxima.org, all this speeding around is getting no one anywhere, just to the grave "faster"(If you wanna say that.)

-Peace

I feel you on this statement....I never say keep it safe cause people will do what they do, i just wish them the best of luck and hope no one is injured. I do a lot of dumbstuff myself and im lucky to have never been in a serious accident at all (knocking on every piece of wood attached to my desk)
